This map is created with tower registration data from the FCC. Since not every antenna structure needs to be registered, the map may or may not list all the towers in the area. In addition, many third-parties own the towers, and lease them to carriers. If this is the case, the carrier may be unknown.

How radiation from mobile phones and towers harm you

 Is there any solid evidence to back the findings that these radiations are harmful to people?

 There are several national and international studies where scientists have found a strong correlation between health problems and exposure to microwaves from mobile phones and mobile towers. Prof Girish Kumar from IIT Bombay had sent a report to Department of Telecommunications (DOT), India which has more than 200 references from peer reviewed publications in the end.

What precautions can you take to reduce your exposure to the radiation from mobile phones?

Some precautions that you can take:

• Limit your use, talk for short durations and switch sides during long conversations. SMS/IM chat whenever possible.
• Use the land-line, whenever possible
• Use speakerphone or wired hands free, but keep the phone at least 1 feet away.
• When not in use, keep the mobile phone away from your body as they still continue to emit some radiation while trying to communicate with the base station by sending at least one pulse per minute. Do not keep it in your pocket, under your pillow etc.
• Use cell phones with lower Specific Absorption Rate (SAR) values. One can find the SAR value of a phone by simply searching- <Company Name> <Model No.> SAR. The lower the SAR value, the less dangerous it is. Ideally go for a phone which has SAR value – 0.2 – 0.8 W/Kg
